This patchset adds regulator support to gpio-keys to ensure that the
regulator powering the Hall Effect sensor IC ("flip cover sensor") is on
when the input device is used.

Marked as RFC because we may want to represent a Hall Effect sensor with
a separate compatible + driver, and not use gpio-keys.

There was also a comment around the usage of of_regulator_get() in the
follow thread:
